Flip station components: Upside down views of the carrier, drive component s omitted.
Flip stationmotor: Viewed from the back of the printer. A pinion on the motor shaft engages the rack at the rear of the carrier, above.
Flip station viewed from above:Points to note:
1. The stop pin (integr al with the rear flipper
arm) rests on the bottom edge of the carrier, alternating from one side to the other in consecutive flip cycles
2.Azimuth adjust rotates the entire assembly to bring the flipper arms parallel to the carriage - a very sensitive adjustment
3.The arms must move freely, without end float. Over tightening of the screws will lock the arms.
Card held by flip arms : As the carriage moves into the flip station, the card slides into grooves in the flip arms. The entire flip assembly is then elevated clear of the platen.
Caution • Cards thicker than 0.033" (0.84 mm) may jam in the flipper arms.
Flip station adjustm ent procedu reThe flip station requires no routine maintenance other than occasional vacuuming out of debris.
Typically, there should be no need to alter the factory settings.
If the flip station ceases to function, or functions erratically, the technician should perform the following tests before replacing components.
1.Power OFF. Remove all cards from the hopper, then close the hopper cover. Disable the main cover interlock so that the printer will function with the cover open. Power ON.
2.On the host computer follow this sequence: Start > Printers (or Printers and Faxes) > Right click Zebra P640i > Properties > Device Settings
> Control > Advanced Utilites
3.Click Move Truck to Flip Station.
4.With the flip arms horizontal, click Flip Test 3 (No Flip) a few times, noting what happens as the carrier begins to elevate at the start of the flip cycle.
This is a test for clearance between flip arms and platen. If the arms touch the platen, even lightly, there will be tendency for one or both of them to rotate a little as the carrier rises. The arms must be parallel to the platen, with a few thousandths of an inch clearance each side. Using a flashlight, check the gap by inserting a 0.004" (0.01 mm) feeler gauge between each arm and the platen. (A narrow strip of regular copier paper can be used instead, but a long metal feeler gauge is better.)
